Roof Top Detectives

It doesn’t take Sherlock Holmes to figure out which of these houses below has the most effective insulation!!  (Hint:  You don’t want to pay for heat to rise out through your attic ceiling and warm your roof.)  Our recent snowstorm provided me a wonderful, yet sad, experience at “reading the roofs.”  Wonderful:  because the rooftops provide such a visual lesson.  Sad, because I live in House E, which has some very strange patterns of melted snow and is one of the worst in insulation.


  1. All of these houses were in the same neighborhood.
  2. All of these houses were facing North, with the same orientation to the sun.
  3. These pictures were taken on late Sunday afternoon, after our snowfall of Saturday afternoon, a full day of sunlight after the snowfall.

Next time the snow falls, find the houses in your neighborhood with roofs that face the same direction as yours.  Watch for the pattern in how the snow melts off the roof.  You’ll soon know which of your neighborhood houses have the most effective insulation.
